4:38pm
in the united states. >> you go out to kansas, you may have a degree temperature difference. that is how most areas are. >> it's one of the main reasons that we have such diverse weather conditions from location to location. we've got a higher terrain in the mountains and hills that help determine wind flow. that shields certain areas from rainfall or from the warming effect of the sun. we've got the ocean and marine influence which generally keeps locations near the ocean cool. >> you look at the south bay, you have mountains on one side and mountains on the other side. there is a reason they get the least amount have rain, it's called rain fade. it goes up the santa cruz mountains, that creates the clouds. the santa cruz mountains rains like crazy down there. conversely, when it comes over and sinks into the valley, it stabilizes the atmosphere and
